Hi everyone. this is my first post and i just started by first restoration project yesterday

Im rebuilding an 1966/67 yds 3 and i have no idea how to wire the ignition switch. i thinker there are 5 positions.

if anyone has a wiring diagram or any idea how this goes, id appreciate it a lot. thanks

dunno but how many ring connectors are there

what colour wires are there

what are the id marks adjacent to the screw connections

do the id marks bear any relation to wire colour

see my signature line

Looks like there are some letters by each screw which would correspond to rge coloured wires. Can you tell what letters they are ?

Usually Yamaha wiring colour codes are :

R = Red

B = Black

L = Blue

R/Y = Red/Yellow

G = Green

Y = Yellow

W = White

O = Orange

Ch = Dark Brown (Chocolate)

There are more but these are the basic ones

Tony

thanks a lot.

the letters are A, B, C, L, & T

i found a wiring diagram for the YL-1 online, which i think tells me 3 (on it B goes to the Battery and is red, L goes to the tail Light and is blue, and C goes to ignition Coil and is brown) , from there i might be able to deduce the rest when i attempt again tomorrow
